However, when excluding the TBAF/DMF-treated probe that showed impedance values comparable to the insulated CNT-control ( Figure 5 B), the correlation was highly significant ( p = 0.017, r 2 = 1.000) with an exponential relation between impedance and residual rubber shield thickness (y = 28.97*e0.151x, r 2 = 0.591; Figure 5 B). 3.2.
